Not according to TfL:

I think TfL is referring to the start of your *Oyster* journey. If you
use a paper travelcard for the first leg, they are saying that you need
to touch in on a yellow reader when the Oyster part of your journey
begins.

and touch out at the end to ensure you pay the appropriate
Oyster single fare and avoid paying a maximum Oyster fare. You can't
touch in on a pink card reader to record the start or end of a journey."

Which is not what I'd be doing. I'd be touching the pink thing to
tell the system that I was switching from travelcard to PAYG halfway
through my journey, not telling it that I was starting a journey.

As far as Oyster is concerned, it is the start of a journey. Oyster has
no knowledge of how you got to the pink reader unless the previous leg
of the journey was also on Oyster.

So, what *are* the pink things for then?

To identify that a PAYG journey has been made via a route that avoids
Zone 1, thus allowing a cheaper fare to be levied, as I understand it.
